In the Book of Genesis, Tamar (; Hebrew: תָּמָר, Modern: Tamar pronounced [taˈmaʁ], Tiberian: Tāmār pronounced [tʰɔːˈmɔːr], date palm) was the daughter-in-law of Judah (twice), as well as the mother of two of his children: the twins Perez and Zerah. Her cunning action in preserving Judah's lineage forms the centerpiece of the narrative of Genesis 38.
